Natural Stacks leading nootropic stack supplement

Neurofuel is the new name for Natural Stacks leading supplement, previously called CILTEP. Neurofuel contains natural ingredients that support mental performance. Its purpose is to influence the internal signal transmission in the nerve cells themselves, rather than your neurotransmitters. It is possible to feel the effects after just 30 minutes.

Vitamine B6 as pyridoxal-L-phosphate
Neurofuel contains pyridoxal L-phosphate, a directly active form of vitamin B6. Vitamin B6 contributes to the normal functioning of the nervous system and supports mental functions, such as learning ability, memory, concentration and reasoning ability. Vitamin B6 also helps to generate energy from fats, carbohydrates and proteins and to reduce tiredness and fatigue.

Artichoke extract
Artichoke (Cynara scolymus) is a vegetable that is common in the Mediterranean area and has been eaten there since ancient times. The 'flower' of the artichoke is most commonly used. Artichoke contains several interesting substances. The substance luteoline is of particular interest for the applications of Neurofuel.

Coleus forskohlii extract
Coleus forskohlii is a herb with Ayurvedic applications. The forskolin substance makes it interesting as part of Neurofuel.

L-Phenylalanine and Acetyl-L-Carnitine
Phenylalanine and carnitine are essential amino acids. Phenylalanine is a precursor to a number of important substances, such as neurotransmitters. Carnitine is part of the mitochondria. Acetyl-L-Carnitine crosses the blood-brain barrier more easily than other forms of carnitine.

Natural Stacks quality
Natural Stacks make the formulation of their supplements completely public. You can find out exactly which ingredients they use for Neurofuel and what the results of their independent tests are. Natural Stacks chooses the highest quality, most active ingredients, something you can check for yourself. Neurofuel is free from gluten and GMOs and is suitable for vegetarians, vegan and paleo.
